  • Method of ion imaging with additional control fields
    Patent number: 3980474
    Abstract: An ion modulator process capable of producing copies of high contrast and with low background utilizes a constant charge density applied in the dark to set up uniform fringing fields which block ions directed towards background (light) areas. Funneling fields are set up in image (dark) areas in opposition to the original uniform fringing fields by simultaneous imaging and ion projection decreasing the effect of such fringing fields and permitting ions to pass through the modulator in image areas.
